GuARDl-:o cA-NA AND CAN-GUARD.

SPECIFICATION forming part of Letters Patent No. 630,443, dated August 8, 1899. Application filed July 11,1898l Serial No. 685,702. (No model.)

To all whom t may concern,.-

Be it known that I, HARRY BITNER, of Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Im, provements in Guarded Cans and Can-Guards, of which the following is a complete specification, reference being had to the accompanying drawings.

The object of my invention is to produce improvements in the means of protecting fragile vessels against injury from outside shock or jar through the employment of a protective covering cushioned against the exterior surface of the protected vessel. In the broad sense of the term a self-cushioned can-jacket is shown in United States Patent No. 536,947, issued April 2, 1895, to Alfred L. Baron. The jacket or protective covering described in that patent consists, essentially, of one composed of interwoven spring-wire spirals, and in carrying my present invention into effect I prefer to employ in its construction a series of spring-wire spirals connected by er woven into a connecting member ormembers, which connecting member or members may oifer more effectual protection against injury to the protected vessel from certain outside blows than that afforded by directly -interwoven spring-wire spirals. i

In the accompanying drawings, Figure I is a perspective view of the upper portion of an ordinary oil-can provided with one form of my protective covering. Fig. II is a horizontal section of aportion of the same. Fig. III illustrates a modified form of envelop* in which a single continuons connecting member is employed as a supportfor the springwire spirals through which it is cushioned to the vessel about which it is employed. Fig. IV is a section on the line IV IV of Fig. III, illustrating the method of uniting the springwire spirals to the single connecting member. Fig. V illustrates a fragment of a further modified form of protective covering in which a series of scalloped connecting members are united or interwoven with spring-wire spirals. Fig. VI is a view similar to Fig. V, showing a further modification in which the connecting members with which the springwire spirals are interwoven are of zigzag form and cut out of sheet metal.

Referring to the iigures on the drawings, 1 indicates a can-body which is presented as an example of a vessel requiringa protective covering.

2 indicates the spout, 3 the filling-cap, and 4 the bail. 4

The parts above enumerated are shown merely by way of example and illustration.

About the ext-erior of the can 1 I employ my protective covering, consisting, essentially, as above set forth, of a self-cushioning jacket of peculiar construction. The peculiar features of itsconstruction consist in the employment of a series of cushioning-strands 5, which respectively make contact at certain points with the exterior surface of the can 1 and serve to support yieldingly out of contact with the surface of the can not only the remainin g portions of the strands 5 themselves, but also the connecting member or members G.

I preferto construct the cushioning-strands 5 in the shape of helices of Wire of suitable resiliency; but the particular form is nonessential, it being sufficient that their shape, whatever it may be, be adapted to perform 'the function of cushioning the main body of the protective covering around, but ont of contact with, the surface of the protected vessel.

The connecting member or members G may be made in a variety of ways. I prefer to employ a separate connecting member between each pair of cushioning-strands 5 (compare Figs. I and II) and to construct the connecting member of a piece of zigzag wire, as illustrated in Figs. I and II.

The particular shape of the connecting memberG, where a plurality of connecting members, as in Figs. I and II, is employed, is non-essential. The connecting member maybe made, for instance, of scalloped plates 7, (see Fig. V,) provided at suitable intervals with perforations 8 for the reception of interweaving or spring-wire spirals 9. In Fig. VI

also I illustrate a zigzag form of sheet metal l10 instead of wire, as shown in Figs. I and II, the zigzag being connected by cushioningstrands ll in a manner similar to that in which the zigzag wire 6 inFigs. I and -II are'united by cushioning-strands.

In the iigures above described a plurality of connecting members is shown by which the cushioning-strands or spring-wire spirals (which is the preferred form of cushioningstrands) are united; but it is obvious that the connecting member may be continuous, as shown, for example, in Figs. III and IV'. In those figures, l2 indicates the connecting member, consisting of a suitably-perforated continuous sheet of metal that is of a somewhat greater diameter than the vessel 13 which it is designed to protect, so that it may duce a covering resemb '2mg that more fully illustrated in Fig. I.

The method of securing the edges Vof my protective covering to the vessel which it protects may be varied at will. The ends ofthe cushioning-strands may, forexample,be gathered together at the top and bottom of the.

vessel substantially in the manner described and illustrated, for instance, in United States Patent No. 536,947, above referred to; but, if preferred, the upper edge of the covering may be finished' with a horizontally-disposed spiral 17, (see Fig. 1,) to which the cushioning-strands 5 and the zigzag wires 6 are united, or, as illustrated in Fig. III, a similar spiral 18 may be employed, connected, however, only to the cushioning-wires 15.

vIVhen the single connecting member 12 is employed, it may, if preferred, be provided with additional perforations for diminishing the weight of the member and also for affording a View from the outside of the contents of the guarded Vessel or receptacle.

What I claim is-- 1. The combination with a vessel, of a protective covering for the same consisting of alternately-arranged and interwoven spring-1 wire spirals and connecting members, the spring-Wire spirals making contact with the vessel, and supporting the connecting mem-V bers out of contact therewith, substantially as set forth.

2. Thecombination with a vessel, of a protective covering for the saine consisting of alternately-disposed and interwoven springwire spirals and zigzag connecting members, the spirals making contact with the vessel and supporting the connecting members out of contact therewith, substantially as set forth.

3. A can-guard consisting of the combination of a connecting member and a series of cushioning-strands of wire Woven therewith throughout the body of the guard, in such manner that the cushioning-strands serve to support the connecting member out of contact with the can, substantially as set forth.

4. -A can-guard consisting of the combination of a plurality of suitably-disposed cushioning-strands radapted to make contact with the can, connecting members interwoven with and uniting the cushioning-strands so as to form therewith a continuous protective covering in which the connecting members are supported by thecushioning-strands out of contact with the can,substan tially as set forth.

5. A can-guard consisting of a plurality of alternately-disposed, interwoven connecting members and cushioning-strands, said cushioning-strands adapted to support the connecting members out of contact with a can, when said guard is applied thereto, substantially as set forth.

6. A can-guard consisting of a plurality of interwoven, alternately-disposed connecting members and spring-wire spirals, the springwire spirals constituting cushioning-strands, and adapted to support the-connecting members out of contact with a can when said guard is applied thereto, substantially as set 7. A can-guard consisting of the combination of a plurality of interwoven,alternatelydisposed, zigzag connecting members and spring-wire spirals, the latter constituting cushioning-strands and adapted to support the connecting members out of contact with a can when said guard is applied thereto, substantially as set forth.

8. In a can-guard, the combination of a' plurality of alternately-disposed,'interwoven zigzag and helical wires, the helical Wires adapted to make contact with a can when said guard is applied thereto, and to support the zigzag wires` outof contact therewith, substantially as set forth.

In testimony of all which I -have hereunto subscribed my name.

HARRY BITNER.
